Butterfly beauty!

My Foldscope has made me increasingly fascinated by insect wings, and so I was very excited when I happened across a couple deceased butterflies that were still in a good enough condition to mount and examine. The first was in a pile of dead leaves in my Cape Town garden, and the second met its end in the grill in the front of my rental car as I was driving from Port Elizabeth to Grahamstown. After reading Aaron’s post on butterfly wings, I am happy to be able to add to the Foldscope butterfly scale library, as well as expose some fascinating butterfly anatomy.

Butterfly 1: Garden Acraea (Acrea horta)


This butterfly is common in South African gardens, as is easily identifiable by its transparent forewings, which are distinct from its bright orange and black hindwings. I mounted a piece of each wing.


The scales on the forewing consist mostly of forked hair-like scales. Scattered amongst them are broader tile-shaped scales, which seemed more prominent near veins.


On the hindwing, the forked scale scales are concentrated at the wing edge, while the rest of the wing is populated with wider tile-shaped scales, coloured black, orange or transparent. The veins form beautiful yellow stripes under the scales.

Butterfly 2: most likely a Cabbage White (Pieris brassicae)


These butterflies were introduced to South Africa, and are common in Cape Town gardens and in the Eastern Cape (where I was driving). I dissected and mounted several parts of the butterfly individually.


The scales on the wings were a beautiful pearly white, streaked with brown and blue patches, as well as strange blue veins.





And finally… the most exciting structure to see was the proboscis. I could clearly see the paired structure, patterned with green and brown, and ending in a beautiful tight spiral. I had no idea that the mouthparts looked this cool up close!

PS I just showed the Foldscope to group of honours students here at the University of Cape Town and they are SUPER excited about it!!! So expect some new Foldscope ambassadors soon…IMG_2507

    Beautiful images! The insect parts on the slide are so nicely organized as well. You might be able to look at specimens in finer detail if you have access to glass or plastic microscope slides (e.g., https://microcosmos.foldscope.com/?p=10184). Alternatively, you could try omitting the layer of tape on top (only using tape on the bottom of the slide to hold things in place), so that the lens is directly viewing the surface of the object.

      Thanks Tom! Good tip! I found another deceased garden acraea butterfly yesterday, this time with its head still in tact so I will try a glass slide to view it this time.

    Hi Dorit!

    What a beautiful and interesting post!

    I wanted to get in touch since I am a new foldscope user who will be traveling to South Africa next week…I have talked to Manu about possibly bringing over some foldscopes and was wondering: do you have any contacts or ideas for groups that might be interested in receiving these and becoming new foldscope users as well?

    I will be in both Cape Town and Johannesburg. If you have some thoughts, I’d love to hear them, either here or over email (maximus.coyle(at)gmail.com)

    Thanks and all the best!

    This is so amazing, wonderful images and very glad you saw the previous butterfly posts. Sometimes instead of placing the whole wing on a slide, I actually remove the scales from the wing with a piece of sticky tape – the scales are lifted off in the same pattern and the Foldscope gets some really crisp resolution. Would love to see more additions!

    Exciting work going on in South Africa. If you have converts more people and think you need more Foldscope units; please send me a “ping” via email.
